American Sign Language: "yell"

The sign for yell
as in "scream," or "call out to."
Hold a loose "C" hand, palm up, near your mouth (sort of as if you
were holding an apple which you were about to take a bite out of)
and then move your hand forward and upward as if representing a
"yell" coming out of your mouth. Match your facial expression to the
intensity of your yell.
